Description

Technical Field

[0001] This invention relates to the field of petroleum processing technology, specifically to a catalytic device that facilitates mixing. Background Technology

[0002] Catalytic cracking of petroleum is a common refining process that uses heat and pressure to break down heavy petroleum molecules into lighter petroleum products. This process typically takes place in the presence of a catalyst. The principle of catalytic cracking is to use the action of a catalyst to cause petroleum molecules to undergo a cracking reaction, converting high-molecular-weight heavy petroleum into lighter products. During the cracking process, carbon-carbon bonds and carbon-hydrogen bonds are broken, thereby forming hydrocarbon compounds with smaller molecular weights.

[0003] According to a public disclosure of a catalytic cracking device for petrochemical production (publication number: CN109135802A), the aforementioned application uses a catalytic cracking device in which a supporting mechanism is internally connected to a catalytic mechanism. The catalytic mechanism contacts the petroleum inside the supporting mechanism, and the catalytic mechanism drives the petroleum to rotate inside the supporting mechanism, increasing the contact area between the petroleum and the catalytic mechanism and accelerating the cracking efficiency of the petroleum. A combustion mechanism is installed on the side wall of the supporting mechanism. During the rotation of the catalytic mechanism, the combustion mechanism sprays flames to burn off the substances on the surface of the catalytic mechanism, keeping the surface of the catalytic mechanism clean. Furthermore, a cleaning mechanism is installed at the bottom of the supporting mechanism to further remove the substances from the surface of the catalytic mechanism, facilitating the rotation of the catalytic mechanism and contact with the petroleum, thereby accelerating the cracking efficiency of the petroleum.

[0004] However, petroleum has a high density. When the catalytic cracking unit first starts operating, the temperature inside is low. Unsaturated compounds in the petroleum solidify at this low temperature, making the petroleum more viscous. This increases the resistance experienced by the motor-driven stirring rod within the petroleum. This increased resistance causes the motor to generate excessive heat, exceeding its design parameters and potentially leading to overheating. Overheating can damage the motor windings and insulation materials, and even pose a fire risk. Summary of the Invention

[0005] The purpose of this invention is to provide a catalytic device that facilitates mixing, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a catalytic device for easy mixing, comprising a cylinder, the cylinder being a catalytic cracking device for petroleum, wherein a stirring mechanism is provided on the surface and inner wall of the cylinder, the stirring mechanism comprising: a motor, a transmission rod, a spring, a limiting block, a connecting sleeve, and an internal gear ring, wherein a telescopic mechanism is provided on the inner wall and surface of the connecting sleeve, the telescopic mechanism comprising:

[0007] The connecting sleeve has a chute on its inner wall. One end of a second spring is fixedly connected to the inner wall of the chute, and the other end of the second spring is fixedly connected to a telescopic rod. A cleaning rod is hinged to the right side of the telescopic rod. One end of a torsion spring is fixedly connected to the surface of the cleaning rod, and the other end of the torsion spring is fixedly connected to the surface of the telescopic rod. The surface of the telescopic rod has a through hole. Initially, due to the low temperature and high viscosity of the raw material, the telescopic rod is on the inner wall of the connecting sleeve. As the temperature inside the cylinder gradually increases and the viscosity decreases, the resistance of the connecting sleeve decreases, and the rotation speed of the connecting sleeve increases. Under the action of centrifugal force, the telescopic rod stretches the second spring and moves away from the second spring, increasing the stirring area. The stirring area increases as the resistance decreases, preventing excessive resistance on the motor. The cleaning rod rotates under the action of resistance, causing the two cleaning rods to form a cone with a smaller angle than a flat angle. This allows the liquid to be pushed up and down by the angled cleaning rods, preventing the liquid from separating into layers.

[0008] Preferably, a motor housing is fixedly connected to the surface of the cylinder, and a transmission rod is fixedly connected to the output shaft of the motor. A groove is formed on the inner wall of the transmission rod, and one end of a spring is fixedly connected to the inner wall of the groove. A limit block is fixedly connected to the other end of the spring. The surface of the transmission rod penetrates the inner wall of the connecting sleeve, and the surface of the transmission rod is rotatably connected to the inner wall of the connecting sleeve. An internal gear ring is formed on the inner wall of the connecting sleeve. When raw materials are fed into the inner wall of the cylinder through the top, the motor is turned on, and the output shaft of the motor drives the transmission rod to rotate. The transmission rod drives the limit block to rotate. The limit block does not initially contact the internal gear ring of the connecting sleeve. The motor output... When the shaft drives the transmission rod to rotate to a certain speed, as an object rotates, it will tilt outward along a curved path. The force generated by this tilting is centrifugal force. Under the action of centrifugal force, the limiting block inside the transmission rod extends out of the inner wall of the transmission rod. At this time, the limiting block stretches the spring, so that the limiting block meshes with the inner gear ring of the connecting sleeve. At this time, the limiting block drives the connecting sleeve to rotate through the inner gear ring. The protruding part on the surface of the connecting sleeve plays a stirring role, so that the motor is in a normal state before connecting the load. At the same time, when the resistance is too large and the rotation speed of the limiting block is too small, the limiting block will stop driving the connecting sleeve to rotate due to the reduction of centrifugal force, thus avoiding damage to the motor due to excessive resistance.

[0009] Preferably, a striking mechanism is provided on the inner wall of the telescopic rod. The striking mechanism includes: a connecting plate, a connecting plate fixedly connected to the inner wall of the telescopic rod, a cylindrical rod rotatably connected to the surface of the connecting plate, a fan blade fixed to the surface of the cylindrical rod, a spring three fixedly connected to the inner wall of the cylindrical rod, and a striking block fixedly connected to the other end of the spring three. When the telescopic rod rotates, the liquid impacts the fan blade through the through hole, causing the fan blade to rotate. The fan blade drives the cylindrical rod to rotate, and the cylindrical rod drives the striking block to rotate. Under the action of centrifugal force, the striking block moves away from the spring three, causing the striking block to extend out of the cylindrical rod and strike the telescopic rod. At this time, the cylindrical rod gains more resistance because the striking block extends out, causing the rotational speed of the cylindrical rod to decrease. At this time, the striking block is pulled back by the spring three, thus repeatedly striking the telescopic rod.

[0010] Preferably, the surface of the telescopic rod is slidably connected to the inner wall of the groove, and the cleaning rods are symmetrically distributed.

[0011] Preferably, the through hole is cylindrical, the transmission rod penetrates the inner wall of the cylinder, and the transmission rod is rotatably connected to the inner wall of the cylinder.

[0012] Preferably, the side of the limiting block away from the second spring is tapered.

[0013] Preferably, the surface of the limiting block is slidably connected to the inner wall of the transmission rod.

[0014] Preferably, the connecting plate is a cuboid block, and the surface of the striking block is slidably connected to the inner wall of the cylindrical rod.

[0015] Preferably, an injection port is fixed at the top of the cylinder, and an output pipe is fixed at the bottom of the cylinder.

[0016] Compared with the prior art, the present invention provides a catalytic device that is easy to mix, and has the following beneficial effects:

[0017] 1. This catalytic device, which facilitates mixing, incorporates a telescopic mechanism. Initially, due to the low temperature and high viscosity of the raw material, the telescopic rod rests on the inner wall of the connecting sleeve. As the temperature inside the cylinder gradually increases and the viscosity decreases, the resistance of the connecting sleeve decreases, and the rotational speed of the connecting sleeve increases. Under the action of centrifugal force, the telescopic rod stretches the second spring, moving away from the second spring. This increases the stirring area, which increases as the resistance decreases, preventing excessive resistance on the motor. The cleaning rod rotates under the action of resistance, causing the two cleaning rods to form a cone shape with an angle less than a flat angle. This allows the liquid to be pushed up and down by the angled cleaning rods, preventing stratification.

[0018] 2. This catalytic device, which facilitates mixing, incorporates a stirring mechanism. When the connecting sleeve rotates, the raw material is fed into the inner wall of the cylinder through the top. The motor is then turned on, and its output shaft drives the transmission rod to rotate. The transmission rod then drives the limiting block to rotate. Initially, the limiting block does not contact the inner gear ring of the connecting sleeve. When the motor's output shaft drives the transmission rod to a certain speed, the centrifugal force generated by the outward tilting of a rotating object along a curved path causes the limiting block to extend outward from the inner wall of the transmission rod under the centrifugal force. At this point, the limiting block stretches the spring, causing it to mesh with the inner gear ring of the connecting sleeve. The limiting block then drives the connecting sleeve to rotate through the inner gear ring. The protruding part on the surface of the connecting sleeve acts as a stirrer, ensuring the motor is in a normal operating state before connecting the load. Furthermore, when the resistance is too high or the rotation speed of the limiting block is too low, the limiting block will stop driving the connecting sleeve to rotate due to the reduced centrifugal force, preventing damage to the motor from excessive resistance.

[0019] 3. This catalytic device, which facilitates mixing, incorporates a striking mechanism. When the telescopic rod rotates, the liquid impacts the fan blades through the through-hole, causing the fan blades to rotate. The fan blades drive the cylindrical rod to rotate, which in turn drives the striking block to rotate. Under centrifugal force, the striking block moves away from the spring three, causing it to extend beyond the cylindrical rod and strike the telescopic rod. At this point, the cylindrical rod gains more resistance due to the extended striking block, reducing its rotational speed. The striking block is then pulled back by the spring three, thus repeatedly striking the telescopic rod. Attached Figure Description

[0028] like Figures 1-7 As shown, the present invention provides a technical solution: a catalytic device for easy mixing, comprising a cylinder 1, which is a catalytic device for catalytic cracking of petroleum. A stirring mechanism 2 is provided on the surface and inner wall of the cylinder 1. The stirring mechanism 2 includes: a motor 21, a transmission rod 22, a spring 23, a limiting block 24, a connecting sleeve 25, and an internal gear ring 26. A telescopic mechanism 3 is provided on the inner wall and surface of the connecting sleeve 25. The telescopic mechanism 3 includes: a groove 31. A groove 31 is formed on the inner wall of the connecting sleeve 25. One end of a spring 32 is fixedly connected to the inner wall of the groove 31. The other end of the spring 32 is fixedly connected to a telescopic rod 33. A cleaning rod 34 is hinged to the right side of the telescopic rod 33. One end of a torsion spring 35 is fixedly connected to the surface of the cleaning rod 34. The other end of the torsion spring 35 is fixedly connected to the surface of the telescopic rod 33. The surface of the telescopic rod 33 has a through hole 36. When the connecting sleeve 25 rotates, the connecting sleeve 25 drives the second spring 32 and the telescopic rod 33 to rotate. At the beginning, due to the low temperature and high viscosity of the raw material, the telescopic rod 33 is on the inner wall of the connecting sleeve 25. As the temperature inside the cylinder 1 gradually increases and the viscosity decreases, the resistance of the connecting sleeve 25 decreases and the rotation speed of the connecting sleeve 25 increases. Under the action of centrifugal force, the telescopic rod 33 stretches the second spring 32 and moves away from the second spring 32, which increases the stirring area. The stirring area increases as the resistance decreases, avoiding excessive resistance to the motor 21. The cleaning rod 34 rotates under the action of resistance, so that the two cleaning rods 34 form a cone with a smaller angle than the flat angle, so that the liquid is pushed up and down by the angled cleaning rod 34, avoiding the phenomenon of layering.

[0029] The housing of motor 21 is fixedly connected to the surface of cylinder 1. The output shaft of motor 21 is fixedly connected to transmission rod 22. A groove is formed on the inner wall of transmission rod 22. One end of spring 23 is fixedly connected to the inner wall of the groove on the inner wall of transmission rod 22. The other end of spring 23 is fixedly connected to limit block 24. The surface of transmission rod 22 penetrates the inner wall of connecting sleeve 25, and the surface of transmission rod 22 is rotatably connected to the inner wall of connecting sleeve 25. An internal gear ring 26 is formed on the inner wall of connecting sleeve 25. When raw material is fed into the inner wall of cylinder 1 through the top of cylinder 1, motor 21 is turned on. The output shaft of motor 21 drives transmission rod 22 to rotate. Transmission rod 22 drives limit block 24 to rotate. Limit block 24 does not contact the internal gear ring 26 of connecting sleeve 25 at first. The output shaft of motor 21 first... When the transmission rod 22 rotates to a certain speed, as an object rotates, it tilts outward along a curved path. The force generated by this tilting is centrifugal force. Under the action of centrifugal force, the limiting block 24 inside the transmission rod 22 extends out of the inner wall of the transmission rod 22. At this time, the limiting block 24 stretches the spring, so that the limiting block 24 meshes with the internal gear ring 26 of the connecting sleeve 25. At this time, the limiting block 24 drives the connecting sleeve 25 to rotate through the internal gear ring 26. The protruding part on the surface of the connecting sleeve 25 plays a stirring role, so that the motor 21 is in a normal state before connecting the load. At the same time, when the resistance is too large, the rotation speed of the limiting block 24 is too small. The limiting block 24 will stop driving the connecting sleeve 25 to rotate due to the reduction of centrifugal force, so as to avoid damage to the motor 21 due to large resistance.

[0030] A striking mechanism 4 is provided on the inner wall of the telescopic rod 33. The striking mechanism 4 includes: a connecting plate 41, a cylindrical rod 42 rotatably connected to the inner wall of the telescopic rod 33, a fan blade 43 fixed to the surface of the connecting plate 41, a spring 44 fixedly connected to the inner wall of the cylindrical rod 42, and a striking block 45 fixedly connected to the other end of the spring 44. When the telescopic rod 33 rotates, the liquid impacts the fan blade 43 through the through hole 36, causing the fan blade 43 to rotate. The fan blade 43 drives the cylindrical rod 42 to rotate, which in turn drives the striking block 45 to rotate. Under the action of centrifugal force, the striking block 45 moves away from the spring 44, causing the striking block 45 to extend out of the cylindrical rod 42 and strike the telescopic rod 33. When the cylindrical rod 42 is struck, it gains more resistance due to the extension of the striking block 45, causing the rotational speed of the cylindrical rod 42 to decrease. At this time, the striking block 45 is pulled back by the spring 44, thus repeatedly striking the telescopic rod 33. The surface of the telescopic rod 33 is slidably connected to the inner wall of the slide groove 31. The cleaning rods 34 are symmetrically distributed. The through hole 36 is cylindrical. The transmission rod 22 penetrates the inner wall of the cylinder 1 and is rotatably connected to the inner wall of the cylinder 1. The side of the limiting block 24 away from the spring 32 is conical. The surface of the limiting block 24 is slidably connected to the inner wall of the transmission rod 22. The connecting plate 41 is a cuboid block. The surface of the striking block 45 is slidably connected to the inner wall of the cylindrical rod 42. An injection port is fixed at the top of the cylinder 1, and an output pipe is fixed at the bottom of the cylinder 1.

[0031] In use, the raw material is fed into the inner wall of the cylinder 1 through the top of the cylinder 1. The motor 21 is turned on, and the output shaft of the motor 21 drives the transmission rod 22 to rotate. The transmission rod 22 drives the limiting block 24 to rotate. The limiting block 24 does not contact the internal gear ring 26 of the connecting sleeve 25 at first. When the output shaft of the motor 21 drives the transmission rod 22 to rotate to a certain speed, since an object will tilt outward along a curved path when it is rotating, the force generated by this tilt is the centrifugal force. Under the action of the centrifugal force, the limiting block 24 inside the transmission rod 22 extends outward. The inner wall of the transmission rod 22 is stretched by the spring of the limiting block 24, which makes the limiting block 24 mesh with the internal gear ring 26 of the connecting sleeve 25. At this time, the limiting block 24 drives the connecting sleeve 25 to rotate through the internal gear ring 26. The protruding part on the surface of the connecting sleeve 25 plays a stirring role, so that the motor 21 is in a normal state before connecting the load. At the same time, when the resistance is too large, the rotation speed of the limiting block 24 is too small. The limiting block 24 will stop driving the connecting sleeve 25 to rotate due to the reduction of centrifugal force, thus avoiding damage to the motor 21 due to large resistance.

[0032] When the connecting sleeve 25 rotates, it drives the second spring 32 and the telescopic rod 33 to rotate. Initially, due to the low temperature and high viscosity of the raw material, the telescopic rod 33 is located on the inner wall of the connecting sleeve 25. As the temperature inside the cylinder 1 gradually increases and the viscosity decreases, the resistance of the connecting sleeve 25 decreases, and the rotation speed of the connecting sleeve 25 increases. Under the action of centrifugal force, the telescopic rod 33 stretches the second spring 32 and moves away from the second spring 32, thereby increasing the stirring area. The stirring area increases as the resistance decreases, preventing the motor 21 from experiencing excessive resistance. The cleaning rod 34 rotates under the action of resistance, causing the two cleaning rods 34 to form a cone with a smaller angle than the horizontal angle. This allows the liquid to be pushed up and down by the angled cleaning rods 34, preventing the liquid from separating into layers.

[0033] When the telescopic rod 33 rotates, the liquid impacts the fan blade 43 through the through hole 36, causing the fan blade 43 to rotate. The fan blade 43 drives the cylindrical rod 42 to rotate, and the cylindrical rod 42 drives the striking block 45 to rotate. Under the action of centrifugal force, the striking block 45 moves away from the spring 44, causing the striking block 45 to extend out of the cylindrical rod 42 and strike the telescopic rod 33. At this time, the cylindrical rod 42 gains more resistance because the striking block 45 extends out, causing the rotation speed of the cylindrical rod 42 to decrease. At this time, the striking block 45 is pulled back by the spring 44, thus repeatedly striking the telescopic rod 33.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
